QWED - Software for Electromagnetic Design

In previous versions of QW-Simulator, status tooltip for radiation pattern results showed frequency, efficiency, radiated power, and radiation resistance. Starting with version 7.5, input power (that is, power actually delivered by the source to the antenna) and input current (in the case of antennas excited by a lumped source) are shown. Small values of input power or current indicate that the antenna is poorly matched to the source, and hence calculations of radiation efficiency and radiation resistance may be ill-conditioned.
